"He told me he was going to kill me several times and I absolutely believed him," she recalled to ET. "I prayed as hard as I've ever prayed for anything ever in my life, and I didn't do anything. I thought, anything I do would escalate the situation -- I couldn't overcome him, he was stronger than me."

Fortunately, she got away and drew a sketch of the man she believed had assaulted her. "I took a pen and I immediately, in shock, like drew a picture of the guy, 'cause I didn't have a camera," she explained. "The guy looks exactly like the thing that I drew."

LAPD confirmed with ET they booked a 45-year-old white male suspect named David Merck on felony battery charges after arresting him at a 7-Eleven in Hollywood.

Not even a day after her attack, the 46-year-old star, who has worked with the homeless in the past, was expressing compassion for those living without a roof over their head. "[My heart] breaks for every single person that's out there on the streets,"she said, "especially [those] with undiagnosed or untreated mental illness."

She also said that after being attacked, she sympathizes more with victims of crime. "I'm a criminal science major. I'm on a crime show, I'm a crime person, but what it actually feels like to be an innocent victim, a pedestrian walking down the street, and be snatched? ...I know what it feels like now and I was terrified," she explained.

Despite her traumatizing experience, Perrette plans on still fighting the good fight. "My life is about helping the homeless and, you know, creating awareness for what's going on," she said. "But every now and then, there's somebody who really is a danger to society, and that guy attacked me."
